Signalling Systems Modernization
Context and challenge
Currently, the 1520 mm gauge network managed by the Customer is equipped with station and interstation traffic management systems of different models made by different Russian, German, Swedish and Czech manufacturers, as well as a Centralized Traffic Control Center made by a Spanish manufacturer in Vilnius. Most station and interstation systems have approached the end of their life cycle, and some systems are no longer in production, some have a limited range of functions and do not have remote control option. In addition, most systems do not have (or have limited) a remote monitoring option and require significant human and financial resources to maintain their secure operation. The operation of different models of traffic management systems causes significant problems for the training of the operation and maintenance personnel, andrequires a very large number of different equipment models and spare parts for repairs and troubleshooting. In some railway stations, mid-century technology facilities, e.g. lockable intercommunication equipment are still used, for which it is no longer possible to obtain parts for repair and extension since the production of such equipment has long been discontinued. The operation of these facilities requires twice and sometimes three times the number of traffic control personnel compared to modern interlocking systems (CBI).
In order to upgrade critically old and worn-out equipment made in Russian and other obsolete traffic management and related systems, to reduce the train schedule violations and costs for traffic management and maintenance of signalling equipment, to increase rail transport safety, train speeds and throughput, and to regulate the pricing of the SLA and Modification of the installed systems and equipment, the Customer seeks to implement the project “Unified Traffic Interlocking System in the LTG’s Network” (hereinafter referred to as the Project), within the framework of which it is being planned to install a uniform-model, modern and functional station and interstation traffic management and related systems with remote monitoring functions of all indoor and outdoor equipment.
